The Beadle - who has smatterings of culture - waxes philosophical:
Werner Heisenberg is out driving when he's stopped by a motorcycle cop.
"Do you know how fast you were going?" asks the cop.
"No, but I know where I am", Heisenberg replies.
René Descartes is drinking in a bar in Paris:
"Another one, René?", asks the barman.
"I think not", says Descartes ... and immediately vanishes.
